Bagaimana cara melakukan validasi baris demi baris pada formulir Oracle APEX Tabular menggunakan Ajax?

Bagaimana saya akan mencoba menyelesaikannya. Perhatikan bahwa ini tidak mencakup semua (ada?) kemungkinan atau banyak penanganan kesalahan. Anda harus menguraikannya sendiri sedikit. misalnya saya menggunakan input untuk pemilih, Anda perlu "pilih". Array mungkin tidak cocok. Anda mungkin memerlukan pemilih yang sama sekali lain seperti by td[headers]. Mungkin objek pengembalian Anda perlu menyimpan nilai lain atau lebih. Js Anda mungkin perlu lebih diperluas.
Namun demikian, js Anda akan menjadi dasar yang baik untuk memulai!

Javascript:

function validaterows(){
  var arrf01 = [], arrf02 = [];

  //fetch all the values from the source columns and put them in
  //a javascript array.
  $("input[name=f03]").each(function(){
    arrf01.push($v(this));
  });

  $("input[name=f04]").each(function(){
    arrf02.push($v(this));
  });

  //provide the constructed arrays to the on-demand process by using
  //the global f## arrays
  apex.server.process ( "MY_PROCESS", {
      f01: arrf01
    , f02: arrf02
  }, {
  , success: function( pData ) { 
      //pData should be an object, because jquery will have parsed the returned json-string
      apex.debug(pData);

      $.each(pData.validationArray, function(index, value){
        if ( value === 'INVALID' ) {
          // do something here when the result is invalid
          // maybe you want to color something red for example
          alert('The data at row '+index+' is not valid!');
        };
      });

      }
  } );
}

  FOR i IN apex_application.g_f01.count

    -- remember: the f## arrays are varchar arrays. Important for comparisons.
    -- Also take into account that the values could NOT be numeric at all.
    -- you'll probably want to run each value through an is-number check or else 
    -- you'll run into ORA errors
    IF to_number(apex_application.g_f01(i)) > to_number(apex_application.g_f02(i))
